Answer:

(2.5, -2)

Step-by-step explanation:

The solution to a <u>graphed</u> system of equations is the point of intersection.

From inspection of the given graph, the two lines intersect at the point (2.5, -2).  Therefore, the solution to the system of equations represented by the graph is (2.5, -2).

<u>Further information</u>

  • If the lines are parallel (they have the same slope) there will be no solution, as the lines will never intersect.
  • If the lines are the same (one line on top of the other line), there will be infinitely many solutions.

A bus travels 36 miles in 45 minutes. How many miles will the bus travel in 60 minutes at this rate. Show a ratio.
ankoles [38]
A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:

rate = 36 miles / 45 min = 0.8 miles per min
distance traveled = 0.8 miles per min ( 60 min ) = 48 miles

HELP Question below in the photo linked
lora16 [44]

Answer:

D. x = 10, m<TRS = 60°

Step-by-step explanation:

m<QRS = 122° (given)

m<QRT = (7x - 8)° (given)

m<TRS = (6x)° (given)

m<QRT + m<TRS = m<QRS (angle addition postulate)

(7x - 8)° + (6x)° = 122° (substitution)

Solve for x

7x - 8 + 6x = 122

Add like terms

13x - 8 = 122

13x = 122 + 8

13x = 130

x = 130/13

x = 10

✔️m<TRS = (6x)°

Plug in the value of x

m<TRS = (6*10)° = 60°
